SKATE.

SPECIFICATION forming part of Letters Patent No. 480,051, dated August 2, 1892.

Application filed March 14, 1892. Serial No. 424,793. (No model.)

To all whom it may concern.-

Be it known that I, JAMES WARNER, of East Somerville, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Skates, of which the following is a full, clear, and exact description.

This invention relates to an improvement in skates of a class that are adapted to be secured upon the feet without straps, and has for its object to provide a skate of the type named which is of a novel, simple, strong, and durable construction, which will be convenient to attach or detach, that will lock fast to the foot forwardly and at the heel, and that is adjustable as to the clamping devices so as to be attachable to foot-coverings of different lengths and Widths.

To these ends my invention consists in the peculiar construction of parts and their combination, as is hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a plan View of the improved skate. Fig. 2 is a reverse plan view, the runner being removed. Fig. 3 is a longitudinal section on the broken line 3 3 in Fig. l. Fig. 4C is a cross-section on the line 4 al. in Fig. 3, and Fig. 5 is a cross-section on the line 5 5 in Fig. 3.

The runner A is slightlycurved and sloped toward the top edge at each end, as indicated in Fig. 3. The foot-ball and heel supports are separate structures, made, preferably, of plate metal cut and bent into shape by proper dies, so as to be rapidly and perfectly produced. The forward support, termed a toe- 4plate, is shaped in contour, by preference,

as indicated at B in the drawings, having a limb a bent downwardly and at an angle rearward, on the end portion nearest to the heel, and at the front end a similar limb h, formed integrally by cutting a portion free to be bent downwardly and forwardly,both limbs being located near the center of width of the toe-plate and notched on their free lower ends centrally of a proper depth and Width to closely embrace the upper edge portion of the runner A, as at c in Fig. 3. There is a toeplate bracket provided, which is also formed by preference of light strong metal plate, consisting, essentially, of two divergent limbs d, that are branched from a transverselyformed hook d below, which hooked portion is centrally slotted through its bow, so as to adapt it to embrace the upper edge portion of the runner A. The limbs Cl of the toe-plate bracket are bent upward and rearward equally distant from the hook portion d and are secured to the lower side of the toe-plate by rivets or other means near to its side edges.

Upon the inner side of the hook portion cl and near its upwardly-bent free end a locking-dog gis pivoted. This piece is shaped like a hook at its lower end and is so fulcrumed that it will have the action of a cam when Vibrated to interlock with the skaterunner by a manipulation of the laterallyextending lever portion of the dog.

A series of suitably-spaced transverse oblong perforations h are formed in the runner A at a proper distance from its front end, which holes incline rearwardly, and above each hole an indentation is made in the upper edge of the runner. (See Fig. 3.) The locking-dog g, from its position,is adapted to enter eitherlof the holes 77, when upwardly vibrated to effect such a connection, this movement drawing the limbs a b of the toe-plate B into close contact with the upper edge of the runner A, and at the same time secures the lower portion of the bracket C to the runner intermediately of these limbs.

The heel-supporting plate D, which engages the runner A at a suitable distance from the toe-plate, is elongated suiciently to admit other parts below it and has two integral limbs t 7c turned down from the front and rear ends of the plate and inclining forwardly, as shown in Fig. 3. The lower ends of the limbs t' 7e are grooved vertically at their center of width to fit upon the top edge of the runner A.

There is a bracket provided, which is located below the heel-plate D, said bracket comprising a cap-plate m and a U-shaped brace m', the latter being attached at right angles to the lower side of the cap-plate and transversely of the same and slotted across its IOO SOP

bow below to iit upon and embrace the upper edge portion of the runner A. There is a series of oblong, spaced, and inclined holes a formed in the runner at a proper distance from its rear end of like dimensions to the holes 7L and serving a similar purpose. The vibratable latch-dog o, which is pivoted to the inner side oi one limb of the brace m', interlocks with any of said holes it may be desired to so engage, and, as shown in Fig. e, the dog named has a cam-hook and a laterallyprojected lever above the hook, whereby the latter maybe rocked to secure the bracket to the runner or release it therefrom.

The heel-plate D is furnished with twotoes p, that are projected upwardly from its rear end near each side edge, and these toes are curved forwardly to adapt their front edges at the top to have contact with the heel of a skaters boot or shoe when the skate is to be secured upon it.

Near the front and at the center of the heel-plate D a slot r of proper width and length is cut, wherein a toe '7" is adapted to slide, this toe being a projecting portion bent at a right angle from the front edge of the cap-plate m.

The heel-plate D and cap-plate m of the bracket below it are further looselyjoin ed by the formation of a longitudinal slot m2 in the cap-plate and the sliding engagement therewith of a capped rivet m3, which is secured in and depends from the heel-plate, the U- shaped brace m having apertures formed in its limbs near to the heel-plate, so as to permit the rivet to slide through and afford a proper range of adjustment.

There is a rearwardly-bent sharpened lip formed on the upper end of the toe 0", as at r2 in Fig. 3, which lip may be caused to engage the front wall of aboot or shoe heel and an embedment of the lip be produced by a forward sliding movement of the heel-plate, which when locked will retain the skate firmly aixed upon the heel of the wearer.

The preferred means for adjustably locking the heel-plate D to retain it and the toe o" in clamped ad justment, as stated, coact with a novel clamping device for the toe- `late B, as will appear. The lmbt' on the front of the heel-plate is horizontally slotted at its center of width to receive the body of a flat bar s, that passes through a similar slot in the rear limb a of the toe-plate, a sufficient length being given to said bar to allow the heel and toe plates to be changed in position as may be required to suit the length of feet of diicrentskaters. There are opposite horizontal slots cut in the upper edges of the limbs cl, where they engage the lower side of the toe-plate B, of proper width to leceivethe curved arms t, which branch oppositely from the point where they have lapped engagement with each other, as at t. The portions of the armst which project at each side of the toe-plate B are bent upwardly at their outer ends and are made slightly concave on the inner faces, so as to insure a tight grip of these toes t2 upon the engaged side edges of a shoe or boot sole. The lapped ends t of the curved arms t are pivoted together and upon an ear on a lever u, that is provided with a curved cam-slotted lateral projection u', and a stud a2, that is aiixed in the bar s below, passes loosely through the cam-slot in the projection u. There is a short longitudinal slot formed in the connecting-bar s below the pivot t3, which connects the ends t of the curved arms t, which pivot passes through the slot mentioned and is cap-riveted at each end, whereby the parts are loosely jointed together, so that a vibration of the main portion of the lever u, which will cause it to project outwardly, as shown by dotted lines in Fig. l, will spread the toes t2 apart, and a folding movement of the lever, as shown by full lines, will draw said toes toward each other and lock them fast upon the side edges of a boot or shoe to which the skate is to be attached, and to avoid improper lateral projection when the skate is so adjusted the lever u is bent, as indicated in Figs. l and2, which will dispose of its main portion close below the heel-plate D.

The slot in the front limb il of the heel-plate D is of sutlicient width, vertically considered, to allow the introduction ot' a wedge between the heel-plate and the connecting-bar s, which will lock the heel-plate upon the bar, and for convenience such a wedge-block is formed on the inner end of the bent lever fu, as at fu in Fig. 3, said lever beingpivoted to the l1eelplate at r2, so that the outward vibration oi' the lever will release the wedge-shaped end that is in locked adjustment when located as represented in Fig. 2.

The surface of the connecting-bar s that is likely to be impinged upon by the wedgeblocl; fu is roughened by any suitable means, so that the inward vibration of the limb of the lever QJ will retain the heel-plate upon the heel of a boot or shoe, if it has been previously driven forward, so as to embed the lip r2 in the front side of the heel and the toes p at the rear, as before mentioned.

It will be seen that from the peculiar construction of parts the entire skate can be produced in quantity by machinery rapidly and perfectly, cheapening the cost and affording a superior device of its class, and the formation of all parts except the runnerfrom plate met-al insures strength with lightness, which are important requisites in metallic skates,` the peculiar method of locking parts together greatly facilitating their necessary adjustment if the appliance is to be Worn by different persons whose feet vary in dimensions.

Having thus described my invention, I claim as new and desire to secure by Letters Patent l. The combination, with the transverselyapertured runner, of the foot and heel plates having depending slotted arms or brackets and a pivoted locking-hook mounted on one IOO IIO
